Can't download the GW2 client.

Hi

So I've done a format on my computer, or whatever it's called, and I'm trying to download the Guild Wars 2 client again. I went to account management and downloaded the file "Gw2Setup", but when I launch the setup the launcher pops up and after a few seconds I get the message "Download failed! Please check your internet connection and try again."

Well. I have internet. I tried launching the setup file as admin. Has anybody else had the same problem?
